Officials are worried of an international crisis as a CIA station chief faces allegations that he drugged and raped at least two Muslim women, ABC Newsreports.

"It has the potential to be quite explosive if it's not handled well by the United States government," Council on Foreign Relations senior fellow Isobel Coleman said. "This isn't the type of thing that's going to be easily pushed under the carpet."

The two known complaints against 41-year-old Andrew Warren, identified in an affidavit for a federal search warrant, were lodged independently of one another in sworn statements to federal prosecutors, prompting U.S. Ambassador David Pearce to order him to return home.

"The U.S. takes very seriously any accusations of misconduct involving any U.S. personnel abroad," acting State Department spokesman Robert Wood said. "The individual is question has returned to Washington and the U.S. Government is looking into the matter."

The woman in the first complaint said that she was raped in September 2007 after being invited to Warren's residence by embassy employees. After being served a mixed drink, she felt the "violent onset of nausea" and was invited to stay the night by Warren. She awoke nude, realizing that she had had sex, but had no memory of it.

The second woman to complain had a similar story, telling authorities that she fell helpless and was stripped naked by Warren after consuming an apple martini prepared "out of her sight" sometime in February 2008.

The warrant was sought after Warren reportedly admitted to having photographs of the two women on his laptop but withheld consent to search it. Investigators later uncovered Valium, Xanax and a handbook on the investigation of sexual assualts from his home. The two drugs are commonly used to "facilitate sexual assault," according to FBI toxicologists. Videos of Warren "engaged in sexual acts" were also discovered.
